> about the mystery of the pearl, a unique gem produced by a living animal
> that requires no mining, extraction, cutting, or polishing to reveal its
> beauty. NOVA travels around the world to exotic locations where rare
> pearls are harvested by divers, and to farms where huge numbers of pearls
> are grown. Will the cultured pearls ruin the value of those grown in the
> wild? From the depths of the ocean to the riches of Fifth Avenue NOVA
> revels in the luster of these desirable gems.
